Cruise Control Switch Indicator Inoperative

Cruise Control Switch Indicator Inoperative

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview
* Review Strategy Based Diagnosis for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions provides an overview of each diagnostic category.

Circuit/System Description

The body control module (BCM) monitors the cruise control indicator switch. When the cruise on/off switch is pressed ON, the cruise control switch is closed and the signal circuit is low. When the cruise on/off switch is pressed OFF, the cruise control switch is open and the signal circuit is high.

Circuit/System Testing

Caution: Refer to Restraint System Service Precautions.

Disable the inflatable restraint steering wheel module when performing this diagnostic. Refer to SIR Disabling and Enabling.

1. Ignition OFF, remove the inflatable restraint steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement (Equinox) Inflatable Restraint Steering Wheel Module Replacement (Torrent).
2. Disconnect the harness connector at the steering wheel controls switch-left.
3. Cruise switch ON, test for less than infinite resistance between the steering wheel control supply voltage and the cruise control indicator dimming signal circuit at the terminals of the steering wheel controls switch-left.

• If the resistance measured is infinite, replace the steering wheel controls switch-left.

4. Test the cruise control indicator dimming signal circuit for an open/high resistance between the BCM and the steering wheel controls switch-left.

• If the cruise control indicator dimming signal circuit tests normal, replace the BCM.
